【摘要】：作為未來(lái)高壩大庫(kù)建設(shè)的代表性壩型之一，近年來(lái)碾壓混凝土壩的建設(shè)規(guī)模不斷提高，筑壩技術(shù)快速發(fā)展，施工設(shè)備不斷革新。勢(shì)必帶來(lái)高強(qiáng)度連續(xù)施工等工程科學(xué)問(wèn)題，給工程設(shè)計(jì)和施工階段的進(jìn)度分析控制帶來(lái)了極大的挑戰(zhàn)。本文圍繞高碾壓混凝土壩施工全過(guò)程仿真、施工進(jìn)度風(fēng)險(xiǎn)分析、施工過(guò)程實(shí)時(shí)動(dòng)態(tài)仿真開(kāi)展了深入系統(tǒng)的研究，主要取得了以下創(chuàng)新性成果。 （1）面向工程設(shè)計(jì)階段，采用系統(tǒng)觀點(diǎn)分析高碾壓混凝土壩施工全過(guò)程，建立了全過(guò)程仿真數(shù)學(xué)邏輯關(guān)系模型，提出了基于施工工藝的施工過(guò)程建模與仿真 針對(duì)傳統(tǒng)的碾壓混凝土壩施工過(guò)程仿真研究重視系統(tǒng)內(nèi)各實(shí)體的狀態(tài)改變和各部分的工序銜接，強(qiáng)調(diào)對(duì)混凝土運(yùn)輸子系統(tǒng)的模擬，沒(méi)有完全準(zhǔn)確地體現(xiàn)施工質(zhì)量控制要求的約束作用，沒(méi)有全面考慮各子系統(tǒng)間的相互制約關(guān)系等問(wèn)題，在對(duì)施工仿真系統(tǒng)進(jìn)行詳細(xì)分析的基礎(chǔ)上，本文建立了高碾壓混凝土壩施工全過(guò)程仿真的隨機(jī)動(dòng)態(tài)數(shù)學(xué)邏輯關(guān)系模型，系統(tǒng)地闡述了動(dòng)態(tài)合倉(cāng)模型、運(yùn)輸上壩模型、倉(cāng)面作業(yè)模型以及系統(tǒng)耦合模型的實(shí)現(xiàn)原理和方法。完善了面向設(shè)計(jì)階段的高碾壓混凝土壩施工全過(guò)程仿真的建模理論與方法。 （2）針對(duì)工程進(jìn)度的隨機(jī)性和不確定性，引入了基于仿真的進(jìn)度風(fēng)險(xiǎn)分析模型——CSRAM，結(jié)合高碾壓混凝土壩施工進(jìn)度計(jì)劃的特點(diǎn)提出了模型的改進(jìn)方法 針對(duì)工程進(jìn)度風(fēng)險(xiǎn)分析領(lǐng)域中常見(jiàn)的理論方法和計(jì)算模型難以考慮工程活動(dòng)相關(guān)性和風(fēng)險(xiǎn)因素相關(guān)性的問(wèn)題，本文引入了基于Monte Carlo仿真的進(jìn)度風(fēng)險(xiǎn)分析模型——CSRAM。結(jié)合高碾壓混凝土壩施工進(jìn)度計(jì)劃的特點(diǎn)，提出了考慮各活動(dòng)涉及的時(shí)間和地點(diǎn)的改進(jìn)CSRAM，實(shí)現(xiàn)了施工網(wǎng)絡(luò)進(jìn)度計(jì)劃的不確定性評(píng)價(jià)。并研發(fā)了相應(yīng)的施工進(jìn)度風(fēng)險(xiǎn)分析軟件系統(tǒng)。 （3）面向工程施工階段，提出了基于實(shí)時(shí)監(jiān)控信息的高碾壓混凝土壩施工自適應(yīng)仿真，分析了相關(guān)建模理論與方法，實(shí)現(xiàn)了施工過(guò)程的實(shí)時(shí)動(dòng)態(tài)仿真 傳統(tǒng)的施工仿真技術(shù)主要應(yīng)用于工程的設(shè)計(jì)階段，不能根據(jù)施工過(guò)程的動(dòng)態(tài)變化進(jìn)行實(shí)時(shí)仿真和進(jìn)度控制。針對(duì)這一局限，本文提出了基于實(shí)時(shí)監(jiān)控信息的高碾壓混凝土壩施工自適應(yīng)仿真。提出了利用施工信息實(shí)時(shí)監(jiān)控系統(tǒng)獲取實(shí)際施工數(shù)據(jù)，分析了實(shí)際信息數(shù)據(jù)的實(shí)時(shí)處理機(jī)制，實(shí)現(xiàn)了仿真邊界的動(dòng)態(tài)調(diào)整和仿真模型的實(shí)時(shí)更新，使仿真系統(tǒng)可以及時(shí)反映施工環(huán)境的動(dòng)態(tài)變化，有效地提高了仿真模型的準(zhǔn)確性。
[Abstract]:As one of the representative dam types in the future, the construction scale of roller compacted concrete dam is increasing in recent years, and the technology of dam construction is developing rapidly. Continuous innovation of construction equipment will inevitably lead to engineering scientific problems such as continuous construction with high strength. This paper focuses on the simulation of the whole construction process of the high RCC dam and the risk analysis of the construction schedule. The real-time dynamic simulation of construction process has been studied systematically, and the following innovative results have been obtained. 1) at the stage of engineering design, the whole construction process of high roller compacted concrete dam is analyzed from the view of system, and the mathematical logic relation model of the whole process simulation is established. The modeling and simulation of construction process based on construction technology are put forward. In view of the traditional simulation research on the construction process of RCC dam, emphasis is paid on the state change of each entity in the system and the connection of each part of the process, and the simulation of the concrete transportation subsystem is emphasized. On the basis of the detailed analysis of the construction simulation system, the constraints of the construction quality control requirements are not fully reflected, and the mutual restriction relations among the subsystems are not considered in an all-round way. In this paper, the stochastic dynamic mathematical logic relation model of the whole process simulation of high roller compacted concrete dam construction is established, and the dynamic closed warehouse model and the transport dam model are systematically expounded. The realization principle and method of warehouse surface operation model and system coupling model are presented, and the modeling theory and method of whole process simulation of high roller compacted concrete dam construction oriented to design stage are perfected. 2) aiming at the randomness and uncertainty of project schedule, a simulation based schedule risk analysis model, CSRAM, is introduced. Based on the characteristics of construction schedule of high RCC dam, the improved method of model is put forward. It is difficult to consider the correlation between engineering activities and risk factors in the common theoretical methods and calculation models in the field of project schedule risk analysis. This paper introduces the schedule risk analysis model based on Monte Carlo simulation, which combines the characteristics of construction schedule of high RCC dam. An improved CSRAM, which considers the time and place involved in each activity, is proposed to realize the uncertainty evaluation of construction network schedule, and a corresponding software system for risk analysis of construction schedule is developed. In this paper, the adaptive simulation of high roller compacted concrete dam construction based on real-time monitoring information is put forward. The related modeling theory and method are analyzed, and the real-time dynamic simulation of construction process is realized. The traditional construction simulation technology is mainly used in the design stage of the project, which can not be real-time simulation and schedule control according to the dynamic changes of the construction process. In this paper, an adaptive simulation of high roller compacted concrete dam construction based on real-time monitoring information is proposed, and the real-time processing mechanism of practical information data is analyzed by using the construction information real-time monitoring system to obtain actual construction data. The dynamic adjustment of the simulation boundary and the real-time updating of the simulation model are realized, so that the simulation system can reflect the dynamic change of the construction environment in time and improve the accuracy of the simulation model effectively.
